|discussion=<p><i>Eriogonum pulchrum</i> occurs as a series of scattered populations north of the Mogollon Rim from northeastern Mohave County, eastward into Apache, Coconino, and Navajo counties; it is found also in northern Yavapai County. It is clearly related to <i>E. ericifolium</i> but is morphologically more distinct from that species than <i>E. thornei</i> is from <i>E. ericifolium</i>. The recognition of <i>E. pulchrum</i> at species rank is a logical extension of the treatment given to Thorne’s wild buckwheat by L. M. Shultz (1998). The species is occasionally seen in cultivation.</p>
